EBR VBA scalability for DR

We are planning to deploy EBR VBA for VM restores at DR site which was backed up from primary site.

- Backup to DD and clone to DR DD using VBA and primary vCenter.

- Restore  VMs using the same VBA in the NW datazone but using the D vCenter.

Is this supported, since the we have metadata in Networker and VBA host and cloned data in DR DD ?

Can someone let me know how we can integrate one VBA host with multiple vCenter ?

Re: EBR VBA scalability for DR

Hi Abul,

Will there be a new / different networker Server be deployed on the DR site as well?

You may need to perform the disaster recovery of the EBR / NVP Appliance ( restore the validated check point on DR Vcenter & add / re-register to the DR Vcenter ).

Not sure if this is tested.

Re: EBR VBA scalability for DR

Since metadata is in nsr server in production, you would require metadata at DR nsr server, you may achieve it by replicating the LUN of metadata in DR site. Get a new VM in DR with the same nsr server name.

Re: EBR VBA scalability for DR

I'm actually on the same predicament.  Customer would like to see how to recover a cloned-VM backed up by EBR.  Based on what you guys are saying, it can't be done unless you fail-over the EBR (and among other things) and re-registering it with the DR vcenter?

Re: EBR VBA scalability for DR

Same here. I have a similar setup and I'm trying to find out how to recovery VM's at an offsite DC during a DR where the primary DC is down. This will be a show stopper for us if I can't do it. I opened up a case with support to see if their is a way.

Re: EBR VBA scalability for DR

Hi Swapnil,

Current scenario (EBR)doesn't support restoring VM's it via different Vcenter (DR Vcenter)

I heard that NetWorker Product team is working out on this.

You can check with Networker support team about the tentative networker release which this is supported.

Re: EBR VBA scalability for DR

Thanks a lot Hari for your prompt response, however I got one more

question, what if I keep the same hostname and ip address at DR for the

vcenter we are already replicating networker server with recover point to

DR site, and our setup supports the same ip addresses at the production and

DR site…. Will it be feasible then???

Meanwhile I will check with the support for more details, but it seems like

you have done quite a lot of research on this so your inputs will be

helpful…

Re: EBR VBA scalability for DR

Sorry for the long delay. I did end up opening up a case and they said the same thing kshariprakash replied. Our Networker SE said their might be a way to change the DNS name of your VBA server that would be recovered to the offsite DC in order to make the offsite vcenter think it was talking to the VBA server at the offsite DC, but he said it's not a support solutions. I have not done any testing on this as of yet. They are working on the issue internally and we were not the only customer asking for a resolution on this issue. I'm still waiting to hear back from our EMC team to find out what solution they will be coming up with.
